I have zcp wheels with 10mm spacer in the back and I am rubbing when i go on really big dips.. The only reason is because I'm running wider tires (advan ad08). I never rubbed with the ps2's I had stock + 10mm spacers. I have pss's on reserve in stock sizes and they don't run as wide as the ad08's, it may be your camber?

My rubbing is occurring with the PSS in stock sizes. The rubbing does not occur with my NT01's due to not running a spacer and the smaller diameter.

It rubs less now but still happens.

It is definitely tire dependant! I had the same set up with PS2 and it never rubbed. Now it rubs with PSS tires which runs wider and is more square.

I am leaning towards using a 5mm spacer instead of the 10mm. I am ok for now but I can't run any wider tire fitment as it is now and afraid of tearing up my tire from rubbing when on track.

I agree, some tires are more likely to rub than others due to thread width and shape of shoulders. I have ran 5 mm spacers previously for some time without any problems. I like the hub-centric 10 mm spacers, but would rather run the 5mm and not have to raise car back to the previous height.
